Questions & Answers about Dar kesim rahatsız değil; bilakis çok rahat.

What does dar kesim mean here?

Literally, dar means narrow / tight, and kesim means section / segment / group.

Together, dar kesim usually does not mean a physically narrow section. In context, it refers to a limited group, a small segment, or a narrow circle of people. It often appears in social or political language.

So dar here has the sense of limited rather than simply narrow.

Why is there no word for is in the sentence?

Because Turkish often leaves out the present-tense copula to be in the 3rd person.

So:

• rahatsız değil = is not disturbed / is not uncomfortable
• çok rahat = is very comfortable / very much at ease

This is completely normal Turkish.
A more formal or emphatic version could be:

• Dar kesim rahatsız değildir; bilakis çok rahattır.

But in everyday and standard written Turkish, leaving it out is very common.
